England captain Andrew Flintoff won the toss and elected to bat in the fourth Ashes cricket test against Australia, giving Shane Warne a chance to claim his 700th test wicket in the first innings.
Warne, whose 699 career wickets is a test match bowling record, is playing his last international match at his home ground, the Melbourne Cricket Ground.
The 37-year-old legspinner will retire after the fifth test next week in Sydney.
Australia has a winning 3-0 lead in the five-match series and retained the same lineup that clinched the series in Perth.
England made one change, with Chris Read coming in for Geraint Jones at wicketkeeper.
"Chris deserves his chance," Flintoff said. Read, 28, has played 13 tests.
Flintoff and Australia captain Ricky Ponting expected the overcast and moist conditions in Melbourne to assist the seam bowlers early.
"There's a bit of weather about, but it's going to be a good deck to bat on," Flintoff said.
"We were a bit down after the last test, but we've regrouped. We're playing for a lot of pride."
Australia is aiming to become only the second team to win a five-match Ashes series 5-0 _ Warwick Armstrong's Australian team was the only other team to do it, in 1920-21.
More than 95,000 people were expected for the opening day of the 100th test match at the MCG.
Australia: Ricky Ponting (captain), Justin Langer, Matthew Hayden, Mike Hussey, Michael Clarke, Andrew Symonds, Adam Gilchrist, Shane Warne, Brett Lee, Stuart Clark, Glenn McGrath.
England: Andrew Flintoff (captain), Andrew Strauss, Alastair Cook, Ian Bell, Paul Collingwood, Kevin Pietersen, Chris Read, Sajid Mahmood, Matthew Hoggard, Steve Harmison, Monty Panesar.
